Abstract
Official abstract text for this publication.
An arrangement for fastening, at multiple fastening points, a power electronic device such as a frequency converter (1) to a base (2) susceptible to vibration, at least a portion of which fastening points are vibration-damped, and which fastening points are on two opposite sides of the frequency converter (1). The invention is realized such that there are at least two fastening points (3, 4; 3, 4, 5) on each of two opposite sides of the frequency converter (1), wherein fastening points (3, 4, 5) on one side are damped while fastening points (3, 4) on the other side are undamped.
First claim
Opening claim text (preview).
What is claimed is: 1. An arrangement for fastening, at multiple fastening points, a frequency converter to a base susceptible to vibration, at least a portion of which fastening points are vibration-damped, and which fastening points are on two opposite sides of the frequency converter, wherein there are at least two fastening points on each of two opposite sides of the frequency converter, wherein fastening points on one side are damped while fastening points on the other side are undamped. 2. The arrangement according to claim 1 , wherein the undamped fastening points include a screw and a base plate, which screw is screwed tightly into the base, and the damped fastening points include a screw, a base plate and a damping bush, which screw is screwed tightly into the base. 3. The arrangement according to claim 1 , wherein there are two damped fastening points and two undamped fastening points. 4. The arrangement according to claim 2 , wherein the frequency converter is substantially in the shape of a rectangle when viewed from above, and the fastening points are located at corners of the rectangle or in the immediate vicinity of the corners. 5. The arrangement according to claim 2 , wherein the material of the damping bush is silicon-based Sylomer SR220. 6. The arrangement according to claim 2 , wherein there are two damped fastening points and two undamped fastening points. 7. The arrangement according to claim 3 , wherein the frequency converter is substantially in the shape of a rectangle when viewed from above, and the fastening points are located at corners of the rectangle or in the immediate vicinity of the corners. 8. The arrangement according claim 3 , wherein the material of the damping bush is silicon-based Sylomer SR220. 9. The arrangement according claim 4 , wherein the material of the damping bush is silicon-based Sylomer SR220.
